I recently started to use genymotion instead of classic Android virtual device, but I have some issues with it.. When I try to run my app I got this error.
Always look at the API Level for an attribute:
<RelativeLayout ... ... android:layout_alignParentEnd="false"/>
android:layout_alignParentEnd was added in API level 17
